FBG-DI-310 Safety evaluation of structures Click images below to see Large Image.          Features - Safety evaluation of structures - Displacement Measurement for the deflection of structures - Displacement Measurement for the crack of structures - Measurement for the contraction and expansion of structures - Measurement for the relaxation of joints of structures - Displacement Measurement for the crack of joints of structures - Built-in FBG Temperature sensor for temperature compensation - Effective cost saving : Compared with other companies of which FBG Displacement Sensors are operated   broad bandwidth in the range of wavelength by using “TWO FBG” sensors, our sensors can be operated at   half of that because they use only "ONE FBG" for Displacement measurement and have high accuracy.   Therefore Interrogator cost can be reduced. Specification - Measurement range : 50, 100 mm (Depending on use's demand) - Resolution : ± 0.05 %F.S - Accuracy : ± 0.25, 0.5, 1 %F.S (Depending on use's demand) - Reflectivity : ≧ 70 % - Operating temperature : - 20 ~ 80 ℃ - FWHM (-3dB point) : ≦ 0.3 nm - Sensitivity : 50 mm > 40 pm/mm   /   100 mm > 20 pm/mm - Dimension : 50 mm > 137 * 50 * 23 mm   /   100 mm > 187 * 50 * 23 mm - Wavelength range : 1,511 ~ 1,590 nm ※ Choose favorable wavelength from the following set division Application cases See Application cases >> Reference Reference File Download >> Advantages -
